Specification of Letters Patent.

Patented April 23, 1907.

Application filed July 1,1905. Serial No. 267,887-

10 tall 1071,0772 it may concern:

Be it known that I, JAooB WALDMAN, a citizen of the United States, residing in the borough of 'Manhattan, New York city, county and State of New York, have invented certain new and useful Improvements in Atomizers, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an atomizer for 'nebulizing liquids and vaporizing and spraying the same by means of an air blast.

The principal objects of the invention are to more effectively draw up the liquid to be subjected to the blast of air, and to more completely break up the particles of the liquid and divide the same into very fine particles so as to produce a very thorough nebulization of the liquid particularly heavy liquids, such as oil, and to increase the effectiveness of the spray accordingly.

With these and other objects in view, my invention consists in the various novel and peculiar arrangements and combinations of the several different parts of the device, all as hereinafter fully described and then pointed out in the claims.

I have illustrated a type of my invention in the accompanying drawings, wherein Figure 1 is a central vertical sectional view of my improved atomizer. Fig. 2 shows a modified form of the air and liquid tube, detached.

Referring to the drawings, in which like numbers of reference designate like parts throughout, 1 is a suitable bottle or vessel for containing the liquid 2, which is to be nebulized or vaporized, and 3 is the screw cap or fitting, made of suitable metal or hard rubber and removably attached by means of screw-threads 4 upon the neck of the bottle so as to cover its mouth in the manner indi cated, a washer 5 of suitable soft material being interposed between the fitting 3 and the edge of the mouth of the bottle to form a liquid tight fit for the same. This cap or fitting 3 is provided with the spray or atomizing tube 6, which at its lower end is in free communication with the interior of the bottle and is provided at its outer end with an ordinary nozzle 7. From one side of the fitting 3 extends a short tubular part 8 to the outer end of which is removably attached the rubber air bulb 9 of the ordinary type and which as well known upon being forcibly squeezed by hand forces or injects the air into the bottle or vessel 1, through the tubular part 8, thence through the air-tube now to be described.

The air-tube 10 is secured in the fitting or cap 3 so as to be in free communication with the tubular part 8, to which the air bulb or pump 9 is attached, and so as to extend downwardly into the interior of the bottle or vessel 1. This air-tube 10 extends a suitable distance down within the vessel and it is closed at its lower end and some considerable distance above its closed end it is provided with a lateral opening or orifice 11. which communicates directly with the interior of the liquid tube 12 which is closed at its upper end 'open at its lower end and in free communication with the liquid contents of the vessel, at a point suitably near the bottom of the vessel. The liquid tube 12 is provided with an orifice 13 of considerably larger diameter or area than the opening or orifice 1'1 and these two orifices are practically opposite each other in substantial axial alignment. In the construction shown, the air-tube 10 and the liquid tube 12 may be made from ordinary tubing of suitable material placed side by side together so as to overlap a short distance and soldered or otherwise secured together in this position, the overlapping of the tubes thus forming a pocket 14 at the lower end of the air-tube and a pocket 15 at the upper end of the liquid tube.

From the foregoing description, it will be readily understood that the blast of air coming from the bulb 9 through the tubular section 8 and the air-tube 10, passes with considerable force through the small orifice 11, across the liquid tube 12 thence out of its orifice 13 into the upper part of the vessel 1. In passing across the liquid tube, this blast of air is passed from the small orifice 11 to a much larger one 13, whence it escapes into the surrounding space in the vessel, thereby tending to create a vacuum within the upper part of the liquid tube and thus drawing up the liquid or oil 2 and breaking it up by the air blast so that the air becomes impregnated with the small particles of the liquid. The liquid thus nebulized or vaporized passes from the upper part of the bottle 1 through the spray tube 6 from its nozzle 7 to be applied as a spray in the usual manner.

While I have shown the air-tube 10 and the liquid tube 12, as being formed together with a common wall between the two and through which the orifice 11 is formed, it is obvious that the same substantial arrangement maybe obtained by modifying the con struction in various ways, though the form which I have herewith shown is exceedingly simple and not liable to get out of order.

In the modified form shown in Fig. 2, the air-tube 10 and the liquid-tube 12 are formed from a single piece of tubing which is bent on itself at the point 16 and again at 17, the part between the two bends 16 and 17 being contracted upon the interior thereof in order to provide a small orifice 18, while just beyond the bend 17 there is formed a larger opening 19 in the wall of the tube 12, directly opposite the orifice 18, and it will be understood that the air being forced down through the tube 10 will pass through the small orifice 18 and then the large-one 19, so as to draw up the liquid through the tube 12 and nebulize the liquid the same as previously described.

It will be noted that in my construction of the spraying tube that the same is practically in one piece and there is a complete absence of any joints and particularly a screw-threaded joint, thereby greatly simplifying the structure and admitting of the tube being kept clean.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. An atomizer provided with a combined liquid and air tube comprising a tubular member projecting into the liquid chamber and having an orifice for directing the air forced through said member in a substantially horizontal direction, and a second tubular member located partially side by side with said first member and adapted to extend partly within the liquid in the chamber and having an orifice in its side opening to the exterior thereof above the liquid level substantially opposite the orifice in said first mentioned member, substantially as and for the purpose set forth.

2. An atomizer provided with a combined .liquid and air tube comprising a tubular member projecting into the liquid chamber and having an orifice for directing the air forced through said member in a substantially horizontal direction, and a second tubular member secured to one side of said first member and overlapping the same and adapted to extend partly within the liquid in the chamber and having an orifice in its side opening to the exterior thereof above the l1qu1d level substantially opposite the orifice in said first mentioned member, substantially as and for the purpose set forth.

3. An atomizer having a liquid tube closed at its upper end and provided near its upper end with a lateral orifice opening to the exterior of the tube, an air tube closed at its bottom and provided with a lateral orifice opening into the side of said liquid tube at a point substantially opposite the first mentioned orifice in said liquid tube and being smaller than said first mentioned orifice;

4. An atomizer having a liquid-tube closed at its upper end and provided near its upper end with a lateral orifice opening to the exterior of the tube, an air-tube closed at its bottom and provided with a lateral orifice opening into the side of said liquid-tube at a point substantially opposite the first mentioned orifice in said liquid-tube, substantially as and for the purpose set forth.

In testimony whereof, I have hereunto set my hand in the presence of the two subscribing witnesses.
